A3000 FUNCTIONAL SPECIFICATION

INTRODUCTION

The A3000 is a cost reduced version of the A2500 personal computer. These cost reductions are achieved by extensive use
of in-house gate array technology, superior packaging and reduced power consumption. Visually, the A3000 is rendered
in a low profile, small footprint case is used with a detached keyboard.

FEATURES
The objectives (features are:)
© 16 Mhz 68030 based CPU w/ 68881 optional (Optionally a 25 Mhz 68030 w/ 68882).
e 1 Meg of Chip Ram, expandable on board to 2 Meg. (32 bit access to CPU).
e 1 Meg of 32 bit wide Fast Ram, (expandable on board to 16 Meg).
e Kickstart in 32 bit ROM (512K).
e Integral 3.5 inch Hard Disk & SCSI controller
e Facilities for 2 3.5 inch floppies.
¢ Real Time Clock.
e Facilities for on board de-interlacer/scan doubler.
e 4100 pin Amiga slots, 2 of which are in line with PCAT slots, and one of which is in line with a new formfac-
tor video slot.
The height and width of the A2000 casework has been replaced by a smaller footprint low profile case. The external floppy
expansion disk connector has been replaced with the SCSI connector. The fan shall be less noisy than that on the A2000.

WHAT’S ADDED

The system now has a 68030 running with 32 bit wide RAM, and 32 bit wide ROM. An on board SCSI controller provides
support for the optional internal hard disk drive, as well as a host of external peripherals such as optical disk drives, etc.
32 bit access to chip memory is provided.

CUSTOM CHIPS

The A3000 CPU will require the use of more custom integrated circuitry than any previous Commodore product. In addi-
tion to the 3 chip Amiga chipset, there are 5 new custom chips.

These include the system glue chip (FATGARY), a new expansion buss controller (FATBUSTER), a new ram controller
with DMA support (RAMSEY), a new improved disk 10 controller (SDMAC), and the D-interlacer gate array controller
part (AMBER).

FATGARY
As the name implies, this chip is a larger version of the gary chip originally used in the A500 CPU design. Fat gary pro-
vides chip select and DASCK support for motherboard resources such as the 8520’s, RTC, chipram, roms and SDMAC.

FATBUSTER.

Fat Buster is a new, larger version of the A2000 chip of the same name. As before, it is responsible for expansion buss con-
trol and arbitration. However, the new buster also maps 32 bit 68030 memory cycles onto standard A2000 16 bit expan-
sion buss cycles. Fat Buster also provides extensions to the standard A2000 16 bit buss protocol which allow full 32 bit ad-
dress and data DMA to occur to and from expansion cards. Thus FATBUSTER allows us to mix and match existing 16
bit A2000 expansion cards, and a new 32 bit card format on the same expansion buss in a wholly compatible manner.

RAMSEY
RAMSEY is a dual function chip. It provides support for up to 16 megabytes of on board 32 bit wide ram, and provides
address generation support for the super DMAC.

SDMAC

SDMAC is a new improved version of the 4701 series of disk & SCSI DMA controllers. SDMAC allows us to provide 32
bit Direct Disk DMA. It is felt that this will yield greatly improved system throughput for large applications, or disk
intensive operating systems.

AMBER
Amber is the name of the Display Enhancer controller gate array. This device, in conjuction with some specialized video
memories, effectively provides a D-interlacer at low cost.

; A3000 SYSTEM SCHEMATICS

SYSTEM IO
The IO capabilities of the A3000 are as follows:

EXTERNAL SYSTEM IO

Serial/Parallel/Mouse/Joystick/Keyboard/Stereo Audio ports
These ports remain unchanged from their A2000 counterparts.

_ SCSI connector
This connector is the same as that found on the back of the 2091 series of hard disk controllers. It allows communica-
tion to a variety of devices including hard disks, optical drives and laser printers.

Video & VGA connectors

As in all Amigas, the A3000 supplies the standard 23 pin video connector. In addition, the on board D-interlacer
provides a standard 15 pin VGA connector.

INTERNAL SYSTEM IO
The following connectors comprise the internal IO capabilities of the A3000.
e SCSI hard drive ribbon cable header
e 4 Amiga slots
2 — PC/AMIGA bridge slots
1 — Amiga slot colinear with video expansion
1 — 1 Amiga only slot
¢ Socketed chip memory expansion good for upgrade from | to 2 meg of chip.
© Socketed fast RAM expansion for upgrade from 1 to 16 Meg.

MEMORY MAP

The A3000 makes use of the full 32 bit addressing capability of the MC68030. In the lower 16 Meg, (the only region
addressable by the 68000), the memory map is basically unchanged from that of the A2000.

$000000- SIFFFFF Up to 2 Megs of Chip Memory

$200000- S$9FFFFF Auto Config Expansion space

$A00000- S$BFFFFF IO Space (8520s)

$C00000- $D7FFFF Location of A500 Magic $C00000 memory. Unused in this machine.
$D80000- $D9FFFF Custom chip register mirror or real time clock.
$DA0000- $DBFFFF Unused.
$DC0000- $DDFFFF Real Time Clock.

$DE0000- S$DFFFFF Custom chip registers.

$E00000- $E80000 Unused.

$E80000- S$E8FFFF Autoconfig slot.

$E90000- $EFFFFF 64k autoconfig slots.

$F00000- $FFFFFF Rom space.

$01000000- $07FFFFFF On board 32 bit ram space. This grows down from $07FFFFFF.
$08000000- $OFFFFFFF 32 bit ram expansion space. This grows up from $08000000.
$10000000-$SEFFFFFFF 32 bit ‘other’ expansion space.

The rom timing circuit provides four different speed settings to match the output enable, and access timing of the

system roms.

To set the jumpers, determine the output enable time, and access times for the roms you wish to use. The rom must

have lower values than for the setting you select.

System standard roms have Toe = 110 ns, and Tacc = 250 ns.
